The TMP112 is a high-accuracy, low-power, digital temperature sensor from TI. It is available in a tiny SOT563 package and requires no external components. It can read temperatures to a resolution of 0.0625°C from 0°C to +65°C with a maximum accuracy of 0.5°C. From -40°C to +125°C, the maximum accuracy is 1.0°C. The TMP112 also has both SMBus and two-wire interface compatibility, allowing up to four devices to be connected to one bus. It also features an SMBus alert function. The TMP112 is ideal for extended temperature measurement in communication, computer, consumer, environmental, industrial, and instrumentation applications.
